What does ichthyologist mean?
An ichthyologist is a scientist who studies fish, including their anatomy, genetics, evolution, behavior, ecology, and distribution. The word is most often used in scientific, museum, university, and conservation contexts, where it identifies a specialist whose work may involve describing species, analyzing specimens, studying habitats, or advising on fisheries and threatened wildlife. Although ichthyologist is relatively uncommon in everyday speech, it is the precise term for someone whose professional focus is fish biology. The closely related noun ichthyology names the field of study itself. In less specialized writing, fish biologist or aquatic biologist may be more natural, depending on the scientist's exact area of expertise.

Where does ichthyologist come from?
The word comes from Greek ikhthys, meaning fish, combined with the suffix -logy, meaning the study of a subject. The professional designation ichthyologist was formed by adding -ist to ichthyology, denoting a person who practices that discipline.
